“North Korean Leader Kim Jong Un just stated that the ‘Nuclear Button is on his desk at all times,’” Mr. Trump tweeted. “Will someone from his depleted and food starved regime please inform him that I too have a Nuclear Button, but it is a much bigger & more powerful one than his, and my Button works!”

The response online was generally one of concern that a subject so stark and potentially catastrophic as nuclear weapons was being blithely discussed on social media by a man who has the power to use them.

This madman is still the single most powerful person on the planet, with the ability to order the destruction of the world in just over four minutes. https://t.co/XIKB23NKQM

Some commentators said Mr. Trump’s tweets Tuesday, which included an announcement that he would name winners of “THE MOST DISHONEST & CORRUPT MEDIA AWARDS OF THE YEAR” next week and a declaration that he was responsible for a record year in global airline safety, were signs something was wrong with the president.

Mr. Trump’s recent twitter storm/interviews are more evidence we’re watching an American president psychologically, emotionally and cognitively decompose. It’s rather alarming to watch, and the president is not well. But at least he’s cutting regulations.

After the CNN host and correspondent Brian Stelter raised the question of whether Mr. Trump had violated Twitter’s terms of service, Dan Scavino Jr., the White House director of social media, accused him of urging that Twitter take action against the president’s account.

Some of the president’s supporters wrote that Mr. Kim, as a dictator responsible for global instability and widespread suffering of his own people, deserved to be insulted, not coddled.

I think the best part about Trump’s “Nuclear Button” tweet, is that all the snowflakes are losing their minds.Not only did Trump offend Little Kim Jong Un, but he also sent the Left into Snowflake Meltdown mode!

Others noted that the “button” that Mr. Trump tweeted about was not actually a button, but a briefcase referred to as “the football.” But there were suggestions that perhaps a button could be introduced.
